Drawing walls - visible only one side

I'm creating my first 3D app in XNA and I have a problem. I created a quad from this tutorial: http://msdn.microsoft.com/en-us/library/bb464051%28XNAGameStudio.10%29.aspx I didn't need any texture for now so I moved quadEffect definition to Initialize and left only this line:

quadEffect = new BasicEffect(graphics.GraphicsDevice);

It is displaying as white wall.

Also I am able to move my camera. It works fine but when i go behind my wall it disappears. What is causing this and how can I make it visible from both sides?

Backface culling is done by default in XNA. If you want to draw the backface of your quad, you will need to set the culling mode:

RasterizerState rs = new RasterizerState();
rs.CullMode = CullMode.None; 

GraphicsDevice.RasterizerState = rs;
